15 Best Sustainable Swimwear Brands for Summer 2025 (Expert-Tested)

Fast fashion swimwear accounts for 40% of fashion’s emissions and can take hundreds of years to decompose, which is surprising. My years analyzing sustainable fashion trends have shown me how these statistics affect our oceans and environment.
